' T all whomit may concern:

Be it known that I, J osnrn A. GRoEBLI, a citizen of the United States, and a resident of the city,-county, and State of New York,

have invented certain new and useful Improvements in Protective Devices for Jacquard-Card-Punchin'g Machines, of which the following is a specification.

My invention relates to protective devices for punching machines by which jacquard cards or patteinrolls are made.

In the making of pattern rolls of paper, for

'use 'in' jacquards it is necessary to guard against placing on the roll perforations for [5 putting into operation at the same time mechanisms operated. by the jacquard, such as the elements of an enibroidering machine, whichwould conflict either in the production of the desired design in theproduct, or

by actual physical conflict between the parts of the machine; Heretofore it has been necessary for the operator to guard against such, occurrences by mental calculation, but in my improved device this is taken care of by an automaticmeans which detects and prevents the machine from placing on. the roll perforations which would conflict the mechanisms operated by the jacquard. This operation is effective both as to immediate changes and parts are effective for the same purpose Where there is a lapse of time be tween the setting into and out of operation of amechanismby the pattern roll.

.Furthermore', part of my improved device consists of certain interlocking means whereby the various operating. elements of the 'jacquardoperated machine will be caused to be set' intoor out of operation with particular reference to the condition of the 4o operating elements of the machine such as operating cams and in-addition to the protectionagainst conflict heretofore referred to.

My invention also provides for the locking of the various means-such as "the levers, by Which the perforations in the roll are caused,

so that there will be no alteration during the actual punching'by the machine.

My present device isan improvement over certain portions of the machine shown in U. SJ'Patent No. 627256, dated June 20, 1899 and I have here illustrated only such parts of the'entire machine as will be necessary to understand my invention, it being understood that the present device may be substitutcd for so much of the mechanism in the said patent as the present device displaces and a complete machine therebv formed. However my present invention may be utilized in other forms of punch ing machines.

Some of the machines which I have invented and which may be referred to as mechanisms which may be -operated by pattern rolls made on my improved punching machine, are shown in I]. S. patents as follows, an examination of which will make the purposes of my present invention better understood-No. 902,817, No. 902,814, No. 902,819, X0. 902,818, dated'Xovember 3, 1908, No. 556,143, dated March 10, 1896 and No. 0l8,458, dated January 31, 1899.

In the making of a pattern roll for embroidering machines there are various punching pins which operate to form apertures in the pattern roll to perform what are the normal functions of the embroidering machine such as the positioning of the tambour frame for the different stitches. There are also other functions to be performed by the jacquard which I have called special functions in my various U. S. patents heretofore ref erred to and these special functions are also represented by perforations in-the pattern roll. The perforations for the tambour frame positioning are taken care of by the machine as shown in my patent to which cross reference has been made herein and of which ."this caseis an improvement. There are a number of setting devices which are adapted to set punching elements in proper. posit-ion for punching perforagms in theroll 1t is only necessary to prevent conflict while the punching is being done, while in other cases a perforationis placed on the roll to place a certain function into operation and leave it in action for a length of time, during which certain other conflicting functions must not'be set into operation, and the coufiicting function punching elements are locked until the first mentioned setting device has been reset and another perforation made to take the function represented by it out of action; when the conflicting meclmnism which had been locked in the meantime,

will be automatically released. 7 In the form of punching machine herein shown and which may be conveniently co mbined with the device shown in my prior patent referred to herein, there are a number of setting devices'which o crate a number of levers to position punc ling elements in the punching device for placing perforations .on the pattern roll-for different purposes.

As herc'shown these setting devices consist ofa number of shafts 1, 2, 3, 4, 5, 6, 7, 8, and 9, which may -representrespectively; the starting or stopping of the machine: the connecting or disconnecting of the embroidering machine;'the, changing of the shuttle action for different stitches; the throwing of 1 he scallop 'nrechamsm into or out of action: for

' throwingthe bore mechanism into or out/of act1on;'lor throwing the stupfel mechanisnr into or out of action; for adjusting the bore mechanism to change the stroke thereof: to adjust; the tension mechanism; and tondiust the take up mechanism. These various shafts are rovided with operating handles which, in t- 1e present illustration so far as the first five shafts are concerned are adapted to be turned from the position on: the left,

determined by the stops '11, a half turn to the right, as determined by the stops 12, to

set the various devices into operation by forming perforations for such purpose in the pattern roll, while. a turn of the levers to the icft takes the mechanisms represented by them out of'action. So that whilcnny of the levers herein referred to are in their right position the mechanisms they repre- ,of the shaft it there is a lever it) whic sent are in action. These several shafts are provided with revolving elements which move therewith and are here shown as disks which revolve and operate the bars which set the punching elements for action through the mechanism shown in my prior patentQ An example of one of the disks may in Fig. 5, which is a rear elevation, wherein the disk is numbered 13 and the lever for settingfthe punching element operated by this disk is numbered 14/ When shaft 2 is revolved a half turn the disk 13 t'hrows bar 14 down to place a perforation on the roll and upon return the bar 14 is raised to place another perforation on the roll,.to put the mechanism thereby represented respectively into and out of action. 'lhese disks differ somewhat according to the number of locking devices to been'gagcd with them. For instance, the upper one 15, is merely to start and stop the machine and need only be locked against accidentalmovement during the punching and therefore has a slot l6, in

)e seen which a lockiugfinge'r17. engages to prevent the rotation of the shaft 1 during the punching of the pm'forntiou in the roll. The linger 17 is moved into or iiiTtof the slot on an oscillating shaft 18 at each punching operation as will appear. As it is desirable to lock all of the aliens setting devices; including the adjusting levers, du ing the punching regardless of any relationship which they may bear to each other this slot 16 and correspondin -finger 17' is duplicated for each of the disks.

The operation of the shaft 18 is caused by the following mecluuusm. ()uthc upderehd l1 rocks the shaft and is supported upon a' small bracket 20, which prevents its free end from dropping. The lever 21, whichis 'l'ulcrumed at 22 to a support is rocked-by the rod which is the rod bearing the same designation in my prior patent and which is moved each time a punch is made by the machine. 'lhc lever 21 has a guiding pocket 23 on the end in which a pin 24 on the lever 19 is engaged by a mall projection 25 in the )ocket 23 and is released therefrom when the rod is operated: There is. a lever 26 operating at '28 which is rocked by a cam 27 on shaft in, which is the shaft similarly designated in my prior patent and at each revolu tion of the s raft the lever 26 is rocked and engages in its upper end with the lever 19 and moves the latter rearwardly until the pin 24 is held by the projection 25 of lever 21 as shown inFig. 5, ready to be released when ever the latter is operz'ited by the rod/ The movement of the lever 19 to the position described is against the action of a spring 29 which has one end statitmarily held at 30 'while the other pulls on a short lever 31,

which, through its connection to'shaft 18 transmits its flCLlOlljiO the lever 19. The

upper partof the pocket. is cutawav at 2.

tions 38, 39, which engage on .opposite sides of a pin 40 and the latter is on a lever 41 which fulcrums at 42. Onthe end of lever 41 there is a pin or bowl 43 which travels in a groove 44 in the face of the cam 45. In 7 this way the revolution of the cam rec1proon .'a slant and when the pin 24 moves in alinement therewith the lever 21 may be rther operated.

Certain of the shafts may be turned by 5 their cranks to the right (see Fig. 1) to cause the perforations representing the different functions to be made, leaving other shaftstat rest in--their first or normal positions. If the machine is now ready for 1 0. punching, the rod g ispulled by the operator-whichwill raise the end of lever :21 and The racks after being raised out of engagement from the pinions are returned to their initial positions,'whether they have been moved to the right or to the left, by the fo owing mechanism; The cam 45 revolves '15 and move the fingers 17 into the slots in the disks and prevent the various disks from rotating during the erforating of the roll so that no; errors will be made by accidental dislocation during the punching: If the set- Q0 ting-handles are not properly or fully pos tioned the fingers 17 will not be able to enter the slots and lever 1 9.will be held back so. thatthe pin. 24 cannot travel to the cut away part 23* and the lever 21' can not be 1 fully 0 erated and the machine started. When t e" unching is completed, the cam 27*will roc thelever 26, which will carry t e lever1'9 rearward again and osition it for the next 0 erationand unloc the va- 30 rious disks, so ar as this mechanism is concemeda Thejdisks on the shafts which re mained'in'their first position will be locked by the fingers 17 moving into the slots 16 .while those on' the shafts which were turned 3i will-be locked by the fingers 17 other slots onlthe 'other sides 'of the disks brought into alin'em'ent with the fingers 17 by the rotation of the shafts.

Certain of the shafts are'provided with 4 pinions 32, Which movetherewith and these punching machine, representing a stitch, and it has two grooves '46 and 47 which are open from opposite sides of the'cam and are disposed on opposite sides of the circumference of the cam and the grooves are adaptedto rock and lock certain levers. There are two ngers may engage the racks no matter what ment. There is one] owlever 52 pivoted to a support and having a pin 56 which enters t e cam groove 46 and is caused to rock thereby. On one end of thelever 52 is connected a short arm 55 on the shaft 48 by which the latter is rocked and locked. Another lever 57 fulcrumed to a support has a pin 58 which engages in the cam groove 47 by which it is locked and rocked similar to 1 the lever 62. but alternately thereto, that is,

is rocked and locked. 5

On the shaft 18 there is loosely mounted a frame consisting of'collars 60 about the shaft from which rojects a series of arms 61 connected by a ongitudinal arm or bar 62 which er of projections 63 which are adapted to be engaged by the racks and the frame thereby rocked. There is also projecting from the frame a series of locl'ing fingers 64 (see Fig.

- appear are for a double purpose. As certam of'the parts of the present mechanism I are a du lication similar numerals will be used for uplicate parts unless otherwise indicated. There are preferably two vertical rods 33, 34, Whlcl are movable vertically and are adapted to be reciprocated in unison to carry the racks out of engagement from .5 their several pinions, to be free to be re-v 8) which are adapted, when the frame is swung, to enter recesses 16 (see 9) in certainof the disks and lock them. There is another frame similar to the one just described, on the opposite side, the parts of which are similarly numbered and whose ngers are adapted to enter recesses 66 in certain of the disks. The frame on the right is loosely mounted on shaft 67. The frame on the right has an arm 68 (see Fig. 4) which engages a similar arm 69 on the opposite frame, whereby rocking of the right frame in one direction will also rock the left frame. A spring 70, isconnected to the bar of the left frame'and to an ear 71, to draw the frames toward each other and into the path of G 1 *o'n'the guiding plates 35 bv which they are rods 33, 34. The rods 33, 34, being connected together may be operated by applying power to one of them. The rod 33, (see Q5 Figs. 2, 3 and 13) has two lateral projecis provided along its inner face with a num- 110 shaft 2 by a strap 72, which is positively oplatter rod is provided with locking fingers 76 ing other fingers 78 which enter-the slots 77 2 7 6. arein the disks the fingers 78 are out an 1 '0 ranged somewhat differently from those of J as follows: There is an arm86 (see Figs. 2

lingers out of the l its normal position,which willcause certai of the disks to be unlocked and-others to locked This construction is duplicated the bar-B4, the parts being numbered 89, 9

and 91 and the same action is caused there by. On shaft 4830 113 of the locking fingers 9 (see Figs 10 and 12) operate to force a spring pressed pin 93 into a disk 94 on shaf 3, so that the scallop mechanism can changed only in certain positions of the ma chine. The rod 95 audits connected mech anisin is not herein specifically claimed a detailed description thereof is unnecessary.

1 In the case of shafts 7-, S, and 9 which ar for causing punches to operate certain adjusting devices in the embroidering machine the shafts are-adapted to be turnedseveral suc-cessive'hall' revolutions in. a given direction and a number in the reversedirection.

To indicate the position of tl'iewadjusting device on the embroidering machine as itis positioned by the punches I haveprovided indicating bars 96, which have racks 97 en.- gaging pinions on the shafts 7, 8 and 9 and these bars are provided with indicating means such as numbers, only one of which on each shows through apertures in the front plate at a time. If the aperture shows the number t' through it the shaft may be turned a half revolution to the left, when number 5 will-show; when a punch is made and the shaftmay be again turned in the same direction untilthe numberfi appears and so on. By turning the shaft to the right the numbers'will be shown in the reverse order, and-indicate at all times the adjustment on the iembroidering machine. have also provided an idlecollar 99 on a pin above the racks 96, which have two downward fingers 100 which lie near or against the uper edges of the rack bars and when either of the shoulders 101 on the, ends of the bars contact with'either of the fingers, the latter will be forced into the recesses-102 and de-l genuine the extreme movement of the rack The operation of my device is as follows; that its locking fingers select differentdisks By reference to some of the embroideringaccording to which ones would set mechanmachine patents it will be seen that at each 50 isms into action which would conflict with' "revolution of the jacquard shaft the operatthe functions caused by the operation of ing cams move certain levers one way and. shaft 3. The rod 84 is also a duplication of return them on the next revolution and the rod 79, it being oscillated by a spring 85 p movable bowls are operated by various F on rod 83 engaging therewith and the fingers 1acquard slides to connect the various bowls on this rod select and lock such disks'as are of the levers with the cams on their two posinecessary. I

After the vrod 79/has been partly operated the racks, and their locking disks, There is another locking element which is operated by certain of the shafts to lock certain other shafts so that their mech anisms can not be operated while the first mentioned shafts are positioncdfor throwing into action the devicesrepresented by their punches. This may be seen in Figs. 8 and 9.

One of the shafts is connected, such as the erated by an eccentric 73 on the shaft, and 18 connected to an arm 74, connected on a collar which is loose on the shaft 67 and by such. connection the rod 7 5. is oscillated. This which enter slots 77 in certain of the disks, say those onshaftsB and 4, from the rear when the bar 75 is rocked by the strap being moved outwardly by the .eccentric and havfrom the front in other disks, say on shaft-s 5 and 6, the fingers 76,-and the fingers 78 being so positioned that. they engage the disks alternately, that is to say, when the fingers vice versa. 'lhereisanother rod 79 which is "loosely journaled on'shaft 57 by means .0 collars similar to the rod 75 and this rod also has alternately engaging fingers, but arrod'75. It has two fingers 80 which enter from the rear into theslots 77 in disks on shafts 5 an d 6 and other fingers 81 which enter other disks, say on shafts 3 and 4, the fin gers 80 and 81 being arranged to act alter nately the same as on thefotherrot The 'rod 75 has a spring 82 whiche' igages by fric .tion with the rod- 79,.which-it revolves with it and the rod'79 is adapted to be returned by the next 0 eration of the cam afterbeing positioned y the rod- 75, whereby only a temporary locking by rod. 79 will be eiiected, in oneof its positions.

I The rod 83 is substantially a duplication. of

- rod 75, it being connected by astrap-and eccentric connection with another 0 the shafts, say on shaft 3, the difference being tions to either connect or disconnect thedif- ,7 PW ferent mechanisms; and the operatipitis of by the rod I cut is returned again by posit ve these bowls must therefore be timed. ii .rblameans and against the friction'oi the spring tion to the revolution of the cams. The cam on my present device operates a half revolution each time which corresponds with a revo lution. of the jacquard shaft of the embroidering machine and therefore pouches for disconnecting and connecting the various levers on the embroidering' machine must be set at andv 10) which extendsiforward and it-has a l V shaped end 87 which is engaged by the arms 88 on rod 33 when tlielatter rises and the contact of the arm 88 with the slanting part of the arm 86 rocks the rod 79 back to lever which engages in the cam 45.

alternate movements of the cam herein. .At each operation of the machine the operator pulls the rod g to cause the punching and this operates through the lever 21 to release the level; 19 when shaft 18 will be rocked by the spring 29, until the locking fingers on the shaft engage in the slots in the disks on the various shafts and lock themagainst accidental movement until the punch is made, no matter in which of their positions the shafts may be. At each operation of the cam 45 the rods 33 and 34 are raised and lowered. If one of the handles on one of the shafts which has arack is turned a half revolution'to the right the rack will be moved to the right and the bar on the disk will operate to set a punching element for action. If the machine is not in proper position for the setting into operation of the function, that is, if cam 45 is not properly positioned for the alternate stitch and the cam on the jacquard is not properly positioned for such action, then the shaft ,48 will be locked, with the fingers 51 in the path of the racks, by the Such locking of the shaft 48 would prevent the turning of a setting shaft to the right until the cam 45 is revolved another half turn and the shaft 48 is unlocked, when the rack will move the fingers 51 in their path. If one or more of the setting shafts are in their right position and it is desired to return it to throw out the mechanism represented thereby, the shaft 49 and its fingers will have the same effect. That is, when the shaft is revolved Kb the left, if the shaft 49 ,is locked, the change can not be madeuntil another half turn of the cam 45. If it is not locked then the fingers 51 will be moved by the rack. If

the setting shafts so operated should be 6 or 7 its rack will engage the projections 63 on frame 62 and rock the latter, whose locking fingers will lock certain of the disks, until the return of the rack to its normal position; If the setting shaftswere turned to the left it would engage one of the projections 63 on the lefaframe 62 and rock it and lock certain disks in the same way. In my device as I have used it the setting shafts which operate the right frame 62 and which operate the left frame do not entirely correspond Each time the racks are operated either to the right or to the left the shafts 48 or 49 with their fingers prevents the setting of the punching. mechanism at the wrong time, the

- shafts being alternately locked and unlocked by cam 45 as described.

When the setting shafts have been set and their racks moved one Way or the-other they are raised out of engagement with the pinions and returned and again engaged ,with the pinions to be moved in the reverse direction the next time the'setting shaft is operated. If a setting shaft has been moved to the right the cam groove,46 ,-on the next movement of the cam will move the lever 52 and through it the shaft 48 will be rocked and its fingers move the rack or racks back to the former position, which is possible when the racks are disengaged by the upward movement of rods 33, 34. The same action will take place on the left side'through the action of shaft 49 and its operating lever, the action of the shafts 48 and 49 alternating. Whenever the shaft 48 is operated, one of its fingers 92 will throw the pin 93 in, to lock one of the shafts making it possible for that shaft to be set only when the cam is in one of its positions.

If the shaft 2 is moved to the right to 0011- I nect the embroidering machine by formin a. perforation for that purpose, it is desira 16 to prevent certain other functions from being started until the next successive'stitch or operation of the cam, while others are to be locked out of action until the embroidering machine is disconnected, which will'be until shaftfl is returned again. turned to the right the strap operated by the eccentric thereon will move the rod and by doing so it will take some of its locking fingers out of some of the disks and enter others in other disks which condition will remain until the return of shaft 2. is moved, the spring thereon will cause the rod 79 to move therewith and this will, so far as this bar is concerned, unlock certain When shaft 2 is When the rod 75 disks and lock others, but this change is only temporary. The next time that the rods 33, 34 raise the arm 88 will engage the V shaped end of the arm 86 on the bar or rod 79 and rockit back toits first position, where it will remain until again operated by the rod 7 5'. Then the shaft 2 is returned the rod 75 will be returned and the first condition restored. The bars 83 and 84 operate similar to the bars 75. and 79, except that they operate from adifferentsetting shaft and efiect a different set of disks.

From the foregoing it will be seen that the setting of the various punching elements is timed in relation to the stitch; that perfora-v tions for conflicting function devices can not be set into operation at the same time and that all the setting elements are locked during the actual punching; and that as to some of the functions there are certain parts in common. Furthermore, by the present combination a number of interlocking devices may be embodied in a single compact,

device and operate independently.
